[U-Boot] [PATCH 0/3] stm32: Add SDRAM support for stm32f746 discovery board

From: Toshifumi NISHINAGA This patch adds SDRAM support to boot Linux kernel for stm32f746 discovery board. Toshifumi NISHINAGA (3): stm32: clk: Add 200MHz clock configuration for stm32f746 discovery board stm32: Add SDRAM support for stm32f746 discovery board stm32: Change USART port

[U-Boot] [PATCH 3/3] stm32: Change USART port to USART6 for stm32f746 discovery board

From: Toshifumi NISHINAGA This change is to remove a halt at about 200KiB while sending a large(1MiB) binary to a micro controller using USART1. USART1 is connected to a PC via an on-board ST-Link debugger that also functions as a USB-Serial converter. However, it seems to loss some data occasion
